HENRY LEIDEL, OF NEV YORK, N. Y.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 558,397, dated April14, 1896.

Application filed J' une 7, 1895.

To all whom it may con/cern.-

Beit known that I, HENRY LEIDEL, of New York city, in the county andState of New York, have invented a new and Improved SafetyBottle-Stopper, of which the following is a full, clear, and exactdescription.

This invention relates to that class of devices known as safetybottle-Stoppers, and designed to prevent the refilling of bottles afterthe contents thereof have once been removed; and the object of theinvention is to provide'a device of this character of a simple andinexpensive construction, which shall present a neat appearance, andwhich shall be adapted to be made of glass or other fragile material, sothat when once applied to a bottle for use it will be in most casesimpossible of removal therefrom without breakage.

The invention consists of a valve-chamber formed or provided at the neckof the bottle, and having a valve-seat and a valve inclosed in saidvalve-chamber, said valve being arranged to open outward, so as topermit the contents of the bottle to be removed, but being adapted toengage said valve-seat when the bottle stands in a vertical position, soas to eifectually prevent any liquid being forced into the bottle fromthe outside.,

The invention also contemplates certain novel features of constructionand combinations of parts, whereby certain important advantages areattained, and the bottle-stopper is made better adapted for use thanother similar devices heretofore employed, all as will be Vhereinafterfully set forth.

The novel features of the invention will be carefully defined in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the gures.

Figure l is a sectional view taken axially through the neck of a bottleprovided with my improved safety-stopper in its preferred form. Fig. 2is a similar view showing a modified form of the device. Fig. 3 is atransverse section taken through the upper part of the stopper shown inFig. 1, and Fig. 4 is a view similar to Figs. 1 and 2, but showing stillanother form of the improved safety-stopper.

Referring primarily to Figs. 1 and 3, 1 indicates the neck of thebottle, 'provided with serial No. 552,013. (No model.)

a plain circular mouth portion 2, the outer side of which is made to iitin a socket formed in the lower portion of a cap 3 forming the body ofthe stopper, which cap as well as the other parts of the stopper will beconstructed of glass.

The cap 3 is annular in form and is slightly enlarged at its upper part,as indicated at 5, and at the base of saidenlarged upper part the cap 3is provided with an interiorly-projecting annular flange 4, adapted to-rest against the top or lip of the bottle-neck, as seen in Fig. l, saidlip being slightly inclined downwardly or coned toward its outer edge toform a chamber or channel into which runs and is retained a smallquantity of liquid for purposes to be hereinafter explained. The cap 3is open at its top and is adapted to be closed by a cover 6, also ofannular form, provided with a central opening 7 and having around itsouter part an annular depending skirt or flange S, concentric with andadapted to t inside the open upper part of the cap 3, as seen in Fig. l,and having its lower edge adapted to form a shoulder or abutment to beengaged by the outeripart of a iiat valve 10, formed of a glass diskarranged in the hollow or valve-chambell 9 of the enlarged upper por.tion 5 of the cap 3. 1

The valve 10 is of a diameter to fit loosely in the circular chamber 9'and is adapted to seat on the inclined upper face of the flange 4 ofthe cap 3, and at diametrically-opposite points in its periphery saidvalve is provided with notched recesses or indentations 11, of a depthsuch that when the valve 10 is in its lowered position (seen in Fig. 1)the passage between the chamber 9 and the interior of the bottle will beclosed; but when said valve is in its raised position and its edgesengage the shoulder 8 of the cover 6, as when the bottle is inverted,passages will be provided Aat opposite sides of the valve, whereat thecontents of the bottle may escape.

The valve will be arranged in the chamber 9 of the cap 3 and the cover Gapplied to said cap and secured in place either by means of cement or bya blowpipe, after which the cap itself may be secured to the bottle-neckin a similar manner, the bottle having first been filled. A cork orother stopper may then be inserted in the opening 7 in the cover 6 andIOO will serve to hold the valve lO in place on its seat and prevent itfrom lrattling about, whereby it might become broken, or a cap may beapplied over the whole device in a well-known way.

Then it is desired-to remove the contents of the bottle, the cork or capis removed therefrom, after which the contents may be poured out in theusual way, the valve 10 falling from its seat by gravity when the bottleis inverted in pouring and returning to its seat by gravity when thebottle is returned to its usual upright position. The inclination of theupper face of the ange or valve-seat 4 servesto collect a small volumeof the liquid, which acts as a seal to close the space left between thevalve 10 and its seat.

Vhen the contents of the bottle have been removed, it will be found tobe impossible to refill the bottle again by removing the cap 3therefrom, since said cap is of a fragile nature and is very securelyattached, thereby rendering its removal without breakage usuallyimpossible, so that it will be seen an eiiicient guard is providedagainst the reiilling of the bottle after its original contents havebeen withdrawn.

The construction shown in Fig. 2 is of a similar nature to that abovedescribed, except that the neck 1 of the bottle is provided with athickened lip 12, having its upper surface beveled or inclined down andoutwardly, as seen at 13, similarly to the flange 4 in the constructionseen in Fig. 1, and for a similar purpose. The cap 3 is unprovided witha fiange 4 and fits over the enlarged lip 12 of the bottle-neck 1, beingsecured thereto by cement or by means of the blowpipe in such a positionas to form a chamber 9 between the upper face 13 of said neck and thetop of .the cap, which is closed, as indicated at 15,

and provided with a central opening 10 and an integral interiordepending flange 14, forming a shoulder to engage the valve 10 and limitthe upward movement of the saine in a manner similar to the flange orskirt 8. The said valve 10 may be of the same construction as the valveabove described, and the device when applied operates in a substantiallysimilar manner to that shown in Fig. 1.

The construction shown in Fig. 4 is very similar to the devices shown inFigs. 1 and 2, except the stopper is adapted to iit the interior of thebottle. In this form of the device the cap 8 is replaced by a cap 1S ofa diame ter adapted to fit the neck 1 of the bottle, which may have alip 17 or be otherwise formed. The cap 18 is provided at its upper partwith an open-topped valve-chamber 9, closed by a cover G ofsubstantially the form shown in Fig. 1 and containing a valve 10 similarto the valve above described. The

valve-seat 21 is beveled and formed interiorly in the cap 18, which isprovided at its lower part with a conical passage 19, leading from thevalve-chamber 9 into the interior of the bottle and controlled by thevalve 10.

The safety-stopper constructed as above described is of an extremelysimple and inexpensive construction, neat in appearance, and is notliable to become deranged or broken by ordinary usage. Moreover, iteffeetually prevents the refilling of the bottle to which it is appliedafter the contents thereof have once been removed.

It is evident from the above description that some modification may bemade in the construction and arrangement of the parts as herein setforth without material departure from the principles of the invention,and for this reason I do not wish to be understood as limiting myself tothe exact form of the device as herein set forth.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentp 1. In a safety bottle-stopper, the combination of a cap having a valve-chamber pro vided with a central valve-seatin its bottom and having its bottom inclined downwardly and outward fromsaid valve-scat to form a channel surrounding the same, a perforatedcover over said valve-chamber, a iiatbot tomed valve in thevalve-chamber to engage said valve-seat, said valve having a diametersubstantially equal to that of the valve-chamber and being provided withnotches in its edges, and a stop to limit the upward movement of saidvalve, substantially as set forth.

2. In a safety bottlestopper, the combina tion of a cap having anopen-topped valvechamberprovided with a valve-seat in its bottom, aperforated cover-plate arranged to fit over the open top of the cap, andprovided with an annular stop on its under side arranged to dependinside the valve-chamber around the outer wall thereof, a valveconsisting of a flat glass plate of a diameter substantially equal tothat of the valve-chamber,

said valve being arranged in the valve-chamber and adapted to engagesaid valve-seat and to play between the valve-seat and the stop on thecover-plate, and having notches in its edges, said notches bein g of adepth adapted when the valve is in its raised position resting againstthe stop on the coverplate to ex tend inside the annular stop on thecoverplate, substantially as set forth.
